Overview

The Water Monitor is a sensor suite that measures 4 properties of water:

Temperature, pH, oxidation-reduction potential (ORP), and electrical conductivity

(EC). The EC sensor may be used to estimate total dissolved solids (TDS). These

measurements can be used for a number of applications. Some suggestions are

laboratory, hydroponics, aquariums, swimming pools, and water-quality field

work. The Water Monitor can be powered using USB-C, or using 3 AA batteries.

Page 2 If you don’t need a certain measurement, you can leave that probe disconnected. The Water Monitor can be powered over USB using its USB-C port, or using 3 AA batteries, which are included in the package. You may use rechargeable batteries, but the Water Monitor will not charge them;...
Page 3 5 minute interval to maximize battery life. Connecting to a PC You can connect the Water Monitor to a PC or Raspberry Pi to send its readings there, by plugging it into the PC’s USB port. The easiest way to take advantage of this is by using the Water Monitor view software, available at https://github.com/...
Page 4 WaterMonitor as an input. Update rate When plugged in, the Water Monitor refreshes readings every second. When on battery power, the update interval is customizable, by using the Update setting in the menu. Setting a longer interval results in improved battery life, at the cost of slower updates.
Page 5 Readings displayed in mS/cm or μS/cm aren’t temperature-compensated: They’re direct conductivity readings. Updating firmware The firmware running on the Water Monitor can be updated to add features, improve performance, or fix bugs. Information on updates, and firmware downloads are available on the AnyLeaf website: https://anyleaf.org/ f irmware-...
